Question 1

What is the Aqara Doorbell Camera G400?

Accepted Answer

The G400 is a wired video doorbell that records in 2K at 1536 by 2048 across a 165 degree tall 3:4 frame, so you see a caller head to toe and a parcel on the floor. It takes power over Ethernet or from existing 8 to 24V doorbell wiring, and it has no battery. Recording goes to a microSD card inside the doorbell with no subscription.

Question 2

What is the Aqara G400 price in the UAE?

Accepted Answer

On 23 September 2026 it was AED 520.00 on Amazon.ae, sold by Kendom and fulfilled by Amazon, with only one unit left in stock. There was no noon.com listing we could verify on the page itself. A microSD card is not included, and the chime needs a USB plug you supply.

Question 3

Where can I buy the G400 in Dubai?

Accepted Answer

Amazon.ae carried it at AED 520.00 when we checked, from the seller Kendom with Amazon fulfilment, but stock was down to a single unit. Stock at that price is thin and the listing can lapse, so if it has gone the unit can be sourced and fitted as part of an installation.

Question 4

Does the G400 need an Aqara hub?

Accepted Answer

No. The G400 joins your network directly over Wi-Fi 6 or Ethernet and sets up in the Aqara Home app on its own. If you already own an Aqara hub such as the M2 or M3 it can sound doorbell alerts through it, but the doorbell does not depend on one.

Question 5

Can the G400 run on batteries?

Accepted Answer

No. The G400 has no battery compartment at all, which is a deliberate design choice rather than an omission. That is what lets it record continuously without draining anything. If you need a wire-free doorbell, look at the battery-capable Aqara G410 or the Aqara Video Doorbell G4 instead.

Question 6

What power and wiring does the G400 need?

Accepted Answer

Three options. Power over Ethernet to IEEE 802.3af at 48V is the cleanest, because one cable carries power and data, and the alternatives are existing doorbell wiring at 8 to 24V AC, 1.3A, 50/60Hz, or 8 to 24V DC, 0.8A. With bell wiring rather than PoE the doorbell still needs Wi-Fi to reach your router, so check signal at the door first.

Question 7

My Dubai home has no doorbell wiring at the front door. What then?

Accepted Answer

That is the normal situation here, and it means cabling is part of the job. In a villa the best answer is usually a Cat 6 run from the network rack or DB to the door, terminated on a PoE switch port. Where that is impractical, a low-voltage transformer feeding 8 to 24V bell wire will also work, but budget for the cable run either way.

Question 8

Is the G400 a DIY install?

Accepted Answer

Not in most Dubai properties. Fixing the bracket to a door jamb, drilling through blockwork, running Cat 6 or bell wire and terminating it at a switch or transformer is an installer's job. If a PoE point and a bracket hole already exist at the door, swapping the unit onto it and adding it in the app takes under half an hour.

Question 9

Does the G400 work with Apple Home?

Accepted Answer

Yes, and it supports HomeKit Secure Video, which needs an iCloud+ plan and an Apple home hub such as a HomePod or Apple TV. One caveat worth knowing before you buy: the stream Apple Home receives is below the 2K you get in the Aqara app, because the tall 3:4 frame carries fewer pixels than Apple's standard format.

Question 10

Does it work with Alexa, Google Home and SmartThings?

Accepted Answer

Yes. Aqara lists Amazon Alexa, Google Home and SmartThings alongside Apple Home for the G400, so you can pull up the door view on an Echo Show or a Nest display. You still set the doorbell up in the Aqara Home app first, then share it to the other platform.

Question 11

Is there a subscription for the G400?

Accepted Answer

No subscription is required. Local recording to a microSD card, person detection and zone intrusion detection all run on the device and cost nothing ongoing. Aqara sells a HomeGuardian cloud plan with a free trial that adds cloud storage and extra AI detection, but the doorbell records and alerts perfectly well without it.

Question 12

Where does the G400 store its footage?

Accepted Answer

On a microSD card of up to 512GB that sits in the doorbell body next to the Ethernet port. The card is not included, so buy one with the doorbell. The G400 can also write to a NAS over SMB and supports ONVIF, which suits a villa that already runs a recorder or a NAS in the rack.

Question 13

Does the G400 record 24/7, or only on motion?

Accepted Answer

It does both. Continuous 24/7 recording is supported when a microSD card is fitted, which is the practical payoff of a doorbell with no battery to protect. Battery doorbells almost always record only in clips around an event, because running the sensor constantly would flatten them in days.

Question 14

Can the G400 handle Dubai summer heat and rain?

Accepted Answer

Aqara rates it from minus 20 to 50 C at 0 to 95% relative humidity, and it is IP65, so rain, dust and the occasional wash-down are not the problem. Direct afternoon sun on an exposed wall is. A surface in full July sun can run hotter than the air, so mount it in a shaded reveal, a recessed jamb or under a porch rather than on bare sunlit wall.

Question 15

What happens to the G400 in a DEWA power cut?

Accepted Answer

It stops, because it has no battery of its own. If it is on PoE you can fix that cheaply by putting the PoE switch and the router on a small UPS, which keeps the doorbell, the network and the recording alive through short cuts. On bell wiring you would need a UPS on the transformer circuit instead.

Question 16

What happens if the internet drops?

Accepted Answer

The doorbell keeps recording to its microSD card and keeps running person and zone detection, because both happen on the device rather than in the cloud. The physical chime still rings over its own RF link. What stops is remote viewing from outside the home, push notifications and any voice assistant that routes through the cloud.

Question 17

What does the included chime do?

Accepted Answer

The chime is a small plug-in unit, 60 by 60 by 23 mm, that rings audibly inside the home over an RF 433MHz link from the doorbell, so you are not relying on a phone alert. It is optional and can be paired or unpaired at any time. It takes USB-C power and no plug adapter is supplied, so add a UK Type-G USB plug.

Question 18

Is the G400 suitable for a rented apartment?

Accepted Answer

Usually not. It has to be screwed to the door frame or corridor wall and fed with either a network cable or bell wiring, which in a tower normally needs the landlord's permission and the building's approval, and the work does not come with you when you move. A tenant is better served by a battery doorbell with an adhesive or minimal-fixing mount.

Question 19

Do I need SIRA approval for a video doorbell in Dubai?

Accepted Answer

Dubai's Security Industry Regulatory Agency regulates video surveillance, and its rules bite hardest on systems that cover public, commercial or shared areas rather than a camera pointed at your own front door inside a private home. If the view takes in a communal corridor, lobby or car park, ask your building management what applies before you install. We make no claim that this product is SIRA approved.

Question 20

How does the G400 compare with the Aqara Video Doorbell G4?

Accepted Answer

The G4 is the flexible one: it runs on AA batteries or bell wiring, records 1080p, and keeps its microSD card in a plug-in chime that also bridges it to the network. The G400 is the fixed-install one: no battery, PoE or bell wiring only, 2K in a taller frame, card inside the doorbell itself, and 24/7 recording. Pick the G4 for an apartment with no wiring, the G400 for a villa with cable to the door.

Question 21

G400 or the battery-powered G410?

Accepted Answer

The G410 runs on six AA batteries or 12 to 24V bell wiring, has a 175 degree landscape view, and doubles as a Zigbee and Thread hub for other Aqara devices. It has no PoE, and its 24/7 recording only works in wired mode. The G400 drops the hub and the battery but adds PoE and the tall head-to-toe frame. Choose the G410 if you want one device to be doorbell and hub, the G400 if you are cabling the door properly.

Question 22

Who should not buy the G400?

Accepted Answer

Anyone renting a flat with no way to run a cable, anyone who wants the doorbell to double as a Zigbee or Thread hub, and anyone who expects full 2K inside Apple Home. It is also the wrong buy if your front door sits on an unshaded west wall with no way to recess or shade it, because sustained surface heat works against a 50 C rating.

Question 23

What warranty applies in the UAE?

Accepted Answer

The Amazon.ae stock comes from a marketplace seller, Kendom, rather than from Aqara directly, so warranty claims normally go back through the seller. Keep the invoice. For units supplied and installed through us, we handle the setup and liaise with the supplier on any faulty hardware.
